A cookie is a small text file a website stores in your browser. We use only two, and both are necessary for the site to function. We use no analytics, advertising or third-party tracking cookies.
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
| tpx_session | Keeps you logged in to the client or staff area. Signing in is impossible without it. | Session, until you log out | Strictly necessary |
| tpx_locale | Remembers the language you are reading in so you need not pick it again each visit. Set when you choose a language, open a link that names one, or your browser asks for one this site is written in. | 1 year | Functional |
| tpx_theme | Remembers whether you chose the light or dark theme. | 1 year | Functional |
| tpx_oauth_state | Protects Google sign-in against forged requests (CSRF). | 10 minutes | Strictly necessary |
| tpx_cookie_ack | Remembers that you have seen this notice (stored in your browser, not a cookie). | Until you clear your browser | Strictly necessary |
Because both cookies are necessary, no consent banner is required. You can delete or block them at any time in your browser settings; you will then need to sign in again and reselect your language.
